免疫避孕是计划生育科学研究的一个重要方面。长久以来,人们就盼望能有一种安全、方便、无副作用、能维持较长时间效果的避孕疫苗问世。如果用作避孕疫苗抗原的分子量较小,则免疫原性差,因而需要与一种大分子蛋白载体进行化学结合,然后通过主动免疫产生抗体,以达到避孕效果。最常用的大分子蛋 Immune contraception is an important aspect of scientific research in family planning. For a long time, people are looking forward to having a safe, convenient and no-side-effect contraceptive vaccine that will last a long time. If used as a contraceptive vaccine antigen smaller molecular weight, poor immunogenicity, and therefore need a chemical bond with a macromolecular protein carrier, and then by active immunization antibodies, in order to achieve the contraceptive effect. The most commonly used macromolecule egg
